Few comments about this set, so here's my five cents.  As a fury warrior, the only piece here that I desire are the shoulders.  T5 dps shoulders paired with the new BoJ bought Furious Deathgrips are my best bet at finding a true dps upgrade to the Ragesteel shoulders/gloves due to the set bonus.  I'm saving arena points for the S3 pants, and I am a 375 Blacksmith/Armorsmith so Bulwark of the Ancient Kings would arrive long b4 the T5 dps chest.  I also have Engineering 376 for the Furious Gizmatic Goggles, so no T5 dps hat for me either.

The set bonus on this truly supports a sword spec MS/flurry warrior.  However, unless she's got the Merciless Glad's sword or Twinblade of the Phoenix, it would be hard to support that build in a raid setting.  T5 tokens are all about raid progression.  Be as self-supporting as you can with your gear, thereby allowing your guildies a better shot at gearing up so you can all progress together.
